Why Choose the Mersen NH2GG40V50 NH Fuse Link?
The Mersen NH2GG40V50 is a dependable DIN NH gG fuse link designed to provide full-range protection for low-voltage cables, conductors and electrical equipment. Manufactured by Mersen, this NH2 fuse link protects circuits against sustained overloads and high-level short-circuit currents in industrial and commercial power distribution systems.
As part of the established Mersen NH gG 400 V AC fuse range, the NH2GG40V50 combines current-limiting performance with a high breaking capacity. This helps reduce the thermal and electrodynamic stresses imposed on switchgear, cables, busbars and connected equipment during electrical faults.
With a rated current of 50 A, a 400 V AC voltage rating and a 100 kA breaking capacity, the NH2GG40V50 is suitable for protecting feeders, distribution circuits and industrial equipment. Its ceramic body, silver-plated copper blade terminals, live gripping lugs and double indication system support reliable operation and straightforward maintenance.

Reliable Protection for Low-Voltage Circuits
The Mersen NH2GG40V50 uses a full-range gG time-current characteristic, enabling it to interrupt currents from sustained overload conditions through to severe short circuits. This allows the fuse link to provide standalone protection for cables, conductors and general-purpose electrical equipment when correctly selected for the circuit.
During a high-current fault, its current-limiting action reduces the peak current and energy passed into the electrical system. This helps protect switchgear, busbars, wiring and connected equipment from excessive thermal and mechanical stress. Installation and replacement should be completed by qualified electrical personnel using an appropriate low-voltage HRC fuse puller.
Typical Applications
- Low-voltage cable and conductor protection.
- Industrial switchboards and distribution panels.
- Commercial electrical distribution systems.
- Feeder and branch circuit protection.
- Industrial machinery power supplies.
- Infrastructure and utility installations.
